How do we > + * fix this? Well, the driver has to copy them :-) Note that v4l2-compliance assumes that there is a 1 to 1 mapping between buffers coming into the codec and buffers coming out of the codec. If that's not the case, then copying such flags does not make any sense. On the other hand, in that case using V4L2_BUF_FLAG_TIMESTAMP_COPY probably makes no sense either.
